To all whom it may concern.' 1

Be it known that THOMAS F. MOORE, a citizen of the United States of America, and resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Loading-Excavators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in loading-excavators or scraperbuckets for excavating and refilling trenches and'similar work, and adapted tobe used more particularly' in connection with overhead trestles and hoisting-and-.conveying apparatus of the class set forth in my pending application, Serial No. 69,217, filed De-e ceinber 29, 1915, in which the back lling proceeds simultaneously with the excavation so as to avoid as far as possible the dangers Of cave-ins, traffic obstructions and other objectionable factors accompanying the old method of piling the excavated materials along the sides of .the trenches.`

Owingbto the factthatdithese trenching operations are carried on very extensively in large cities and other districts where trafhc is more or less congested, it becomes necessary to restrict the width as far as may be consistent with eiiicient and economical work, and in most places requires that the walls of the trench be cut perpendicular and reinforced by sheathing and cross braces or stays arranged at suitable intervals for retaining the sheathing'in place, thifs preventing movement of the walls .of the trench.

`Under such conditions, the availableworking space is extremely limited and prohibits -tlie use of many implements, such for eX- simultaneously disconnected therefrom preparatory to hoisting and conveying it along the superposed trestle to the rear of the encavation or other locality where I it is dumped,

Another Vobject is to provide suitable power-operating means for manipulating the bucket into and out of the scraper and also for impelling the scraper along the trench in eitherdirection with or without the bucket therein.

` A further object is t A provide the scraper with suitable cutters for blocking out ther load and defining the sides of the trench.

Other objects and uses relating to specific parts of the device will be brought out in the following description.

In the drawingsi Figure l is a ltop plan of a lOading-eXca vator embodying the main features ofv my invention, a portion of the front-top plate or hood being broken awa-y to show the underlying plow points, and showing also the forward draft cables forthe scraper and bucket which are assembled for digging and loading` Fig. 2 is a front end View of the device shown in Fig. l, except that the'draftcables are omitted.

Fig, 3 is a longitudinal vertical sectional view taken on line 3-8', Fig. l, omitting the draft cable for the Scraper and showing the rearward draft cables and connections for drawing the entire device backwardly and tilting. the loaded'b'ucket to an upright position.

Fig. 4 is a side elevation of the same de-- vice showing the bucket as tilted to an upright position relatively to the scraper ready for hoisting, the dotted lines above the bucket indicating its partially hoisted position, while the draft cable for the bucket `is shown by dotted lines as detached therefrom to allow the attachment of the hoisting cable thereto.

.Fig 5 is a side elevation ofthe same scraper and bucket, the front portion of the scraper being broken away, while the bucket is in position to be tilteddownwardly andforwardly to the position. shown by dotted lines for telescoping interlocking coni' nection with the scraper as the bucket is ,drawn forwardlyby its draft .cable into the rear end of the scraper.

As illustrated, this loading-excavator coniprises a scraper -l--`, a bucket #2, forward draft cables -3- and de for drawing the bucket into operative relation to the scraper and 'for drawing the scraper and bucket forwardly for tilling the bucket, and a rearward'draft cable 5- for tilting the loaded bucket to an upright position relatively to the scraper preparatory to hoisting, the cable -5- being also pro videdwith a hook, as -6-, adapted to be connected to the rear end of the scraper for drawing the latter with or without the loaded bucket therein rearwardly.

rlhe scraper and .bucket are preferablymade of-sheet or rolled steel or other suitlthe opposite side plates, as -8-, whichare `'of substantially the same length as the bottom, but are preferably LL-shape and spaced a suliicient distance apart to receive the 'bucket between them, the portionsJV of the sides at 'their junctions with the bottom being curved in cross sectionv to correspond with the curved corners of the bucket.

rlphe upright portions of the sides 8 Vrise from the front end of thebottom to a vheight substantially equal to or slightly greater than that of the bucket' when thie latter is supported upon said bottom, an( are somewhat wider from front to rear than the vertical height of their remaining portions which extend rearwardly therefrom to the rear edge ofthe bottom. n

The side plates -8- are provided with lforwardly projecting fender plates llhaving their rear ends riveted or otherwise secured to the outer faces of the front ends of the plates -8- and their forward endsextendingvsome distance beyond thel front edge of the bottom to form fender plates for trimming the side walls of the trenches and deecting the material into the bucket as it is loosened by the digging or plow' points presently described.

rlhe upper front, edges of the fender plates *94' incline forwardly 'and downwardly from the upper front 'edges of the side plates 8- and are reinforced by angle ironsl0- which in turn* are "connected by a cross plate or hood 1L- aiid a front erom bar l2- the'ends of the latter being extended downwardly alon'g the outer sides of the front ends of the fender plates w9- and maarre walls of the trench by shearing cuts.

ilhe top vplate or hood. 11.- extends from-the cross bar l2 rearwardly beyond the front edges of the plates -S and l serves to deflect the material which may be loosened by the scraper into the front open end of the bucket -2- when the latter is placed -in operative position upon the scraper.

il reinforcing plate-- of substanstantially the same width as the upright secured 'by rivets or other suitable fastening means to the under side of the front end of the bottom -Tw and extends some distance beyond the opposite longitudinal edges of said bottom and terminates in down- Awardly and outwardly deflected flanges The lower edges of .the rear ends of the fender plates -9- are extended downwardly and outwardly beyond the`plane of the bottom .-T- to formflanges dl-` parallel with the flanges #l5-'1, but spaced apart therefrom. i

Suitable plow points or diggers -l7- are interposed between and secured to the flanges -15- and 46 so as to stand at the corners of the bottom and sides of the scraper, their digging points being extended -forwardly some distancebeyond the front edge vof lthe bottom for the purpose of blocking out the loose material and facilitatin-g its entrance into the open end of the bucket as the whole device is drawn forwardly., these corner blades or diggers 1.7 also serving to block out and define the sides of the trench so as to provide ample clearance for the sides of both scraper and bucket and allow the latter to descend more readily to the bottom of thetrench by theirown weight;

uniform distances apart from each other and from the corner plow points ml? and are also provided with beveled front ends projectingl forwardly some distance beyond the front edge of the bottom for loosening the earth or other material and facilitating its passage into the open end of the bucket.

soA

Yportions of the side plates -,8- is -rigidly ll0() edgewise in downwardly diverging planes The front ends of the angle irons -10 y and overlying portions of the cross bar l2- are. apertured for receiving pivotal bolts QD-J to which are attached a pair of clevises for receiving -the rear ends oflthe draft cables -lby which the apparatus as al Whole may be drawn forwardly for loosening the earth and* loading it into the bucket.

Attached to the hook -6- is a clevis -22- adapted to be attached to the rear end of the scraper -7- by means of a pin` the scraper with the roller directly; underl the center thereof, as shown morerc'learlyk in Fig. 3, thus preventing the rear end of the scraper from digging into'the bottom of the trench.y

rlhebucket -2- is ofthe bottom-dump.

type open at the top and substantially rectangular in cross section, except that its corners are rounded, the bottom, as --26-, being hinged at --27-- to one side to swing outwardly and may be held in its cl-osed position by any suitable form of latch -28- not necessary to herein illustrate or describe.

The interior of the bucket is divided by a central lengthwise partion -29- arranged in a plane at right angles to the axis of movement of the bottom and secured to the opposite walls of the bucket for bracing the same, the upper end of ,the partition being provided with apertured ears or lugs BO- for receiving a hook 3lon the end of the cable -3- by which the bucket is drawn into the scraper, and also for receiving asimilar hook on a hoisting cable, as -32--, shown by dotted lines in Fig. el. i

The hinges -27- project outwardly beyond the corresponding side and bottom of the bucket and are adapted to drop into openings S3- in the bottom T- 'of the f scraper near the rearend thereof as the bucket is drawn on to-said bottom with its front end in engagement with the rea-r so as to estab-- edges of the-diggers '18 lish interlocking Iconnection between the bucket as the latter is drawn forwardly by the scraper in the operation of digging and loading.

- These cooperative interlocking connections, viz z-the hinge @27- and opening -33- also serve as limiting stops to hold the bucket against undue rearward movement and to constitute a fulcrum therefor in the act of tilting the loaded bucket from a horil.zontal to an upright position, the latter' being accomplished by means of a hook 3lon one end of the cable 5 in a manner presently described.

.In operation` the empty bucket is lowered into the trench at a point just at the rear of the scraper lor in a position similar to that shown in Fig. 5, whereupon the hook `3l of the cable -3- is attached .to the ears --3O--- and the hook 34M of the cable -5- is also attached to the bucket in the manner shown in said figure. The cable -/lis then drawn forwardly by any suitable' operating means, thereby tensioning the cable and tilting the bucket forwardly and downwardly onto the bottom of the scraper, the continued forward movementI of the cable serving to draw the bucket forwardly upon said bottom until its forward end encounters suitable stops.

in this instance the rear ends of the diggers have entered the openings B3- At thev beginning of this operation of cables 'lare slackened but are so ad- `justed as to be tensioned at about the same tinie'that the forward end of the scraper engages the stops, so'that the continued forward movement. of the draft cable places both the cables" -3- and .-lunder tension to exert a' forward pull' upon both the'scraper and bucket.

This forward movement of the scraper with the empty bucket therein lcauses dirt or .other material to be loosened and diverted into the. bucket, such movement being continued until the bucket is filled, whereupon the cables -3- and lmay be slackened and the cable 5 then wound upon a suitable engine-driven drum, not shown, for tilting the bucket right-side-up tothe position shown in Fig. l, the interlocking connections between the; hinges -27 and openings -33- of the bottom of the scraper serving as a fulcrum about which the bucket is tilted to its upright position. y

The hoisting cable -32- from the superposed traveling conveyer or other hoisting device is then lowered and hooked into the apertured ears -30- of the bucket, and

the 'hoisting apparatus on said conveyer is Before the bucket is hoisted and carried to place of discharge, an empty bucket may almost any trench, and at the same time per-v mits either to be used independently of the i other if necessary, as for example in hand loading, in which case the plow will be simply used for looseningthe material in the trench.
